The principal aim of neurointensive care in patients with intracranial tumor surgery is prevention, prediction, early detection, and the prompt treatment of postoperative complications. Maintenance of proper hemodynamic and adequate respiratory support is necessary to prevent postoperative mass effect due to cerebral edema, hydrocephalus, hematoma, and infarct causing cerebral herniation syndromes. Invasive blood pressure monitoring is usually recommended along with measuring intracranial pressure to allow the proper evaluation of cerebral perfusion pressure and an effective cerebral blood flow. For the effective neurocritical intensive care of surgical patients with brain tumors, good harmony, interaction, and communication between the neurosurgeon and the neurointensive team is of paramount importance.
